Awesome idea. We had a lot of issues with termites at our last house so I'll definitely use cypress!
Yes as Clissa pointed out there are certain edibles you can underplant in an orchard - Eden style - and it's very pretty plus useful.Soo, I just cant decide!!
Orchard seperate to the vegetable patch in rows with a ring of mulch vegetable patch in raised beds
Or
Orchard amongst vegetable patch to create a large garden bed that isnt raised.
What are your thoughts?
